"Therefore, Bohr advocated the use of both pictures, which he called 'complementary' to each other. The two pictures are of course mutually exclusive, because a certain thing cannot at the same time be a particle(i.e., substance confined to a very small volume) and a wave (i.e. a field spread out over a large space), but the two complement each other. By playing with both pictures, by going from the one picture to the other and back again, we finally get the right impression of the strange kind of reality behind our atomic experiments." (Heisenberg, Physics and Philosophy, p. 23)
"That is to say, the primary 'mistake' that can be made in this field is not the positive one of wrongly assigning what originates in thought to a reality independent of thought. Rather, it is the negative one of overlooking or failing to be aware that a certain movement originates in thought, and thus implicitly treating that movement as originating in non-thought. In this way, what is actually the one single process of thought is tacitly treated as if it were split in two parts (but of course without one being aware that this is happening). Such unconscious fragmentation of the process of thought must lead to distortion in all of perception." (Bohm, Wholeness and the Implicate Order, p. 78)
So you are agreeing that the video proves your statement false then? The video is not of sand sitting on my kitchen table, is it?

Pour some sand on your table at home and wait.
I guarantee they will not start behaving uncertainly and statistically, interfering with one another to produce interference patterns etc. They will not form the cymatics patterns without the wave in the medium.
I haven't ruled out the pilot wave interpretation though apparently some people have. I don't think anybody has really proven which interpretation is correct so until it's proven, I'd say the jury is still out. My "position" as you put it, is to look at observations and experiments as a means of revealing how nature really is.
If you want to call the particles separate from the waves and REAL, but the waves are actually representing something REAL also - then you are taking the position that there is like a 'guiding wave' or 'pilot wave'. That would say that there could be the particles, but their actual wave behavior is due to some objectively real and deterministic 'hidden variable' (the 'pilot wave').

Complementarity is a mainstream view. You may be surprised that I'm not going to try to defend it as the only possibility. There may be other possibilities.

How can two mutually exclusive realities be 'complementary' to each other? I'll tell you: In our imagination.

As for what's real, the probability density plots that were shown in the image in my post have been measured repeatedly. So at least in the sense a photograph of an object is a real representation of whatever was photographed, it's showing us something real, but in the sense that it's only a photograph, it's not the real object, as the probability density plots only give us a "picture" so to speak, using that analogy. A picture of my house is not my house, but it's a pretty good likeness of it. Likewise the probability density plots of electron orbitals are pretty good representations of where we expect to find the electron when we observe it. I don't really know exactly how electrons move inside atoms or what their structure is when we aren't looking at it, we can only say that when we look at it, here's where it is. That's what the probability density plots show for many observations.
But they’re also waves, right? Then what are they waving in?
It’s interesting, isn’t it? That has hung people up ever since the time of Clerk Maxwell, and it’s the missing piece of intuition that we need to develop in young people. The electron isn’t the disturbance of something else. It is its own thing. The electron is the thing that’s wiggling, and the wave is the electron. It is its own medium. You don’t need something for it to be in, because if you did it would be buffeted about and all messed up. So the only pure way to have a wave is for it to be its own medium. The electron isn’t something that has a fixed physical shape. Waves propagate outwards, and they can be large or small. That’s what waves do.
So how big is an electron?
It expands to fit the container it’s in. That may be a positive charge that’ s attracting it—a hydrogen atom—or the walls of a conductor. A piece of wire is a container for electrons. They simply fill out the piece of wire. That’s what all waves do. If you try to gather them into a smaller space, the energy level goes up. That’s what these Copenhagen guys call the Heisenberg uncertainty principle. But there’s nothing uncertain about it. It’s just a property of waves. Confine them, and you have more wavelengths in a given space, and that means a higher frequency and higher energy. But a quantum wave also tends to go to the state of lowest energy, so it will expand as long as you let it. You can make an electron that’s ten feet across, there’s no problem with that. It’s its own medium, right? And it gets to be less and less dense as you let it expand. People regularly do experiments with neutrons that are a foot across.
A ten-foot electron! Amazing!
It could be a mile. The electrons in my superconducting magnet are that long.
A mile-long electron! That alters our picture of the world—most people’s minds think about atoms as tiny solar systems.
Right, that’s what I was brought up on—this little grain of something. Now it’s true that if you take a proton and you put it together with an electron, you get something that we call a hydrogen atom. But what that is, in fact, is a self-consistent solution of the two waves interacting with each other. They want to be close together because one’s positive and the other is negative, and when they get closer that makes the energy lower. But if they get too close they wiggle too much and that makes the energy higher. So there’s a place where they are just right, and that’s what determines the size of the hydrogen atom. And that optimum is a self-consistent solution of the Schrodinger equation.
Complementarity is a mainstream view. You may be surprised that I'm not going to try to defend it as the only possibility. There may be other possibilities.
However I also see it as a problem when people try to infer that because things behave a certain way in the macro world, that they should necessarily exhibit similar behaviors on an atomic scale. This to me seems to be the basis in that quote for claiming complementarity must be false. It is not a persuasive argument at all to me. So the best I can say is that there may be alternatives to complementarity. I can't say it's wrong, and indeed it may very well be right.
I'm not sure which side you're arguing on here. The electrons don't make those shapes in the probability density plot all by themselves. They only do it when they are part of an atom.

I'd say they are still probability density plots. I never said they couldn't represent more than that, but I don't know what you mean by "actual quantum wave field". What are the measurables and the properties of this such that I can confirm this claim in the lab?
What if I told you those weren't probability density plots, but mean representations of an actual quantum wave field.
I'm somewhat "agnostic" in this regard, though I have what I suppose are philosophical problems with the "many worlds" interpretation, but if enough evidence was presented to support that's really the way it is, I could accept it. I just doubt the likelihood of that being the case.

I don't think you realize quite what the 'mainstream' view actually is. You seem pretty reasonable, and I would think you would agree with someone like Mead over someone like Bohr and Heisenberg. Please read the Mead interview.
In a way I gave you the answer to that. Calculate the DeBroglie wavelength of an electron in a double-slit experiment. Then calculate the DeBroglie wavelength of a baseball. Then try to find the "cutoff point". Mathematically, there is no exact "cutoff point. But you can see that what happens to the wavelength calculations as the particles get larger and larger. Have you tried this? I have. It's an exercise worth doing if you want to know the "cutoff point" between quantum and macro. You run the numbers and you tell me where the numbers say the cutoff point is. You agree that the electron exhibits wavelike interference in the double slit experiment, and that this has never been demonstrated with baseballs, correct? I think the double slit experiment has been performed with buckyballs, and if so then the cutoff point is somewhere between the size of a buckyball and a baseball. I don't know how much larger than a buckyball we can go, and still do the double slit experiment successfully, but I doubt that's the absolute maximum upper limit; it's just the largest so far.
Where does this divide between 'micro' and 'macro' come from? Is that distinction 'real'? Is it meaningful?
So are you saying that now we do understand what the hell is going on? While the Copenhagen interpretation seems to be somewhat preferred, I really don't see people claiming it's proven. I still see more experiments taking place, with explanations that the new experiments still don't prove which interpretation is correct but they may be making some progress.
'Complementary' is not something in nature. It is a philosophical idea proposed in a theory in order to make more sense of what appeared to be non-classical data in the early years of quantum theory. It was a fudge factor introduced by Bohr because everyone at the time didn't understand what the hell was going on.

It wasn't posted as an example of what happens inside the atom. It was posted to illustrate that Beebs' claim was false.

I'm not trying to say this video either is or is not a model of what happens on the atomic scale, I'm only showing it as an example that your generalizations are wrong. Particles can indeed appear in densities shaped like waves, even if the particles themselves aren't waves. This video proves that doesn't it?
Whether a car or a ball, the forces acting on a body moving in a straight line are very different to those acting on one moving in tight curves. This maxim also holds true at microscopic scales. As such, a beam of electrons that moves forward linearly has different properties to one with vortex-like properties. Since vortex beams show properties in magnetic fields that could lead to novel applications, a RIKEN-led research team has developed a theory that provides an understanding of these properties.

The vibrating table covered in sand is a completely wrong analogy to compare with an atom.
If you look at an atom, you'll something quite different. The field (in a good approximation for this discussion) is a spherically symmetric Coulomb field. It does not possess "nooks and crannies" to be occupied by unsuspecting electrons.

Prove it?
You are saying that elections and atoms are not within a field..most specifically a field that demonstrates geometry.

Yes, avoiding the question, avoiding an answer, avoiding backing up your statements with real proof.
not surprised.
Can you prove that there is no geometry involved in fields?
